I want to upgrade to Bioconductor 3.6. I followed the instructions to upgrade R (I have 3.4.2), and source("https://bioconductor.org/biocLite.R"). However, it shows 3.5 still. Running biocLite() does not change this.

I tried removing the biocInstaller package as was suggested by some, but that did not get me to 3.6

Users of R-devel / bioc-devel will experience issues for the next hour or so; windows users of R-devel will need to install from source for the next day or so (at least some CRAN windows binaries seem to be built with R-3.4.2 instead of R-devel).
